Abstract
The utility model relates to a high-temperature resistant cable for a gas-guide sensor, comprising an insulated wire formed by arranging an FEP (fluorinated ethylene propylene) insulating layer outside a tinned copper conducting wire core, and a cable core formed by arranging five insulated wires and three FEP filled cores at the periphery of the FEP gas-guide tube, wherein a first teflon film inner lining layer, an inner jacket formed by weaving glass silk, a shielding layer formed by weaving tinned circular copper wires, a second teflon film inner lining layer and an FEP jacket are sequentially arranged outside the cable core. The high-temperature resistant cable for the gas-guide sensor is characterized by good weldability and corrosion resistance, ensures the electrical insulating property of the cable and guarantees the stability of chemical stability, and mechanical and physical resistance under extreme environments. The high-temperature resistant cable for the gas-guide sensor ensures that the material property of the gas-guide tube is identical with that of the insulating layer; and the high-temperature resistant cable has the capabilities of accurately monitoring the liquid level and pressure. The high-temperature resistant cable for the gas-guide sensor is characterized by high heat resistance, and outstanding oil resistance, solvent resistance and corrosion resistance, good moisture resistance and irradiation resistance as well as excellent oxidation resistance, low temperature resistance, and the like.
Description
Technical field
The utility model relates to a kind of private cable, particularly a kind of detection system matching used high temperature resistant air guide sensor cable that links to each other with transducer that is suitable under the industry extreme environments such as petroleum works, mining, water conservancy.
Background technology
High temperature resistant air guide sensor cable has the function of transmit communications signals, conducting pressure displacement information, possesses good anti-electromagnetic interference and mechanical resistance pulling force function simultaneously.And common air guide sensor cable generally can't bear high low temperature, extreme environments such as oil, acid soak.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of high temperature resistant air guide sensor cable.Its temperature resistant grade-60 ℃～+ 200 ℃.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of high temperature resistant air guide sensor cable, it is characterized in that: be included in the tin-coated copper conductor wire core insulated wire that one deck perfluoroethylene-propylene insulating barrier constitutes is set outward, constitute cable core at five insulated wires of perfluoroethylene-propylene wireway peripheral arrangement, three polyfluorinated ethylene filled cores, outside cable core, be provided with screen, polytetrafluoroethylene film second layer inner covering and the perfluoroethylene-propylene sheath of polytetrafluoroethylene film ground floor inner covering, braided glass filament inner sheath, the braiding of zinc-plated circular copper wire successively.
Characteristics of the present utility model are: high temperature resistant air guide sensor cable, be that a kind of transducer that tolerates extreme environment connects private cable, conductor thread core is the low tin-coated copper conductor of resistivity, not only guarantees the electrical property of conductor, and has good solderability and corrosion resistance.Insulating barrier is a perfluoroethylene-propylene, has not only guaranteed the electrical insulation capability of cable, and guarantees that cable has chemical-resistant stability and mechanical and physical performance under extreme environment.Wireway adopts the perfluoroethylene-propylene consistent with insulating barrier, guarantees that wireway has with insulating barrier identical materials performance and has liquid level, pressure monitoring ability accurately.Filled core adopts the perfluoroethylene-propylene consistent with insulating barrier, and the interpolation of filled core makes and the Stability Analysis of Structures of cable kept whole roundness and consistency of performance, and the employing tubular structure, has reduced the weight and the material consumption of cable.First inner covering adopts polytetrafluoroethylene film, has both guaranteed the roundness of cable, play a protective role again, and film thickness is very thin, has guaranteed the entire outer diameter of cable.The Weaving type inner sheath adopts glass braid, except that very high mechanical strength is provided, also has higher electrical insulation capability, the thermal endurance of better chemical stability, and moisture absorption is little.Zinc-plated circular copper wire braiding is adopted in the Weaving type shielding, and processing technology adopts the multiply type of weave to increase flexibility, and has reduced external diameter, and high count makes this product have extraordinary anti-electromagnetic interference capability, can play a protective role again simultaneously.Second inner covering adopts polytetrafluoroethylene film, in the rounding property requirement that guarantees cable, plays buffer action simultaneously again.Sheath adopts perfluoroethylene-propylene, and it has the thermal endurance of height, outstanding oil resistance, anti-solvent and resistance to wear, good moisture-proof and radioresistance, characteristics such as good non-oxidizability and lower temperature resistance.
